Ektron CMS400.Net Reference
You can assign an image to any content item’s metadata. It is a standard field automatically available to every content item. It is not a definition in the Metadata fields.
Use the Image field to identify an image that can be retrieved by Ektron Markup Language’s (EKML) [$Image] and [$ImageThumbnail] variables. See Also: Controlling Output with Ektron Markup Language.
An example of using Image data is a list summary that includes a photo of every item on the list. For example, your site promotes a soccer team. The list summary shows every player on the team. To the left of each player’s name is a thumbnail of his image.
